[llvm-dev] FYI, we've posted a component of Spectre mitigation on llvm-commits

[Leslie Zhai via llvm-dev]

Hi LLVM developers,

Does it need to implement <Target>RetpolineThunksPass, 
`getOpcodeForRetpoline`, `EmitLoweredRetpoline`, etc. for other Targets? 
Or does it also need to implement `RetpolinePic` to inherit from 
<Target> for LLD's Backends? Alex is my mentor, he is leading me to 
maintain RISCV target, so I have such question, please give me 
suggestions, thanks for your teaching!
